UNITED STATES PATENT OFFICE MOTOR VEHICLE LOCKING DEVICE Anthony H. Burski, Chicago, Ill.

Application July 24, 1947, Serial No. 763,315

1 In the operation of a motor vehicle, it often happens that the driver forgets to release the emergency brake before starting the vehicle, and asa consequence the brake is subjected to a friction of great intensity which often starts fire or "causes serious damage to the vehicle. Therefore, the principal object of the present invention is the provision of a locking means, in co-operation with the emergency brake operating handle, for

locking a selected part of the vehicles operating mechanism, such as clutch operating bar or the --like, which; when locked simultaneously with the operation of the emergency brake handle, will prevent the starting of a vehicle until the emergency brake'handle is brought to an inoperative position in order to release the clutch operating bar or other mechanism.

A still further object of the present invention is the provision of a locking device of the type struction, combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing forming a part of this application and in which like designating characters .refer to corresponding parts throughout the several views;

s Fig. 1 is a cross-sectional view, longitudinally of the body of a motor vehicle, with the side elevation of the present device and in co-operation with the clutch operating bar and the emergency brake handle;

Fig. 2 is an enlarged face elevational view with the locking device in an operative position;

Fig. 3 is a similar View showing the locking device in a withdrawn, inoperative position; and

Fig. 4 is a side elevational view of the locking device.

Referring in detail to the present drawing, there is shown therein a motor vehicle body, including floor I0, foot board II and dashboard I2. The latter two separate the tonneau and the engine compartment. Positioned forwardly of foot board II is clutch operating bar I3, provided at its upper end with arm I4 which is extended through said foot board I I. Said arm I4 is provided with pedal I5 for resting drivers foot, whereby the pressure exerted upon said pedal I5 will shift said '2 Claims. (01. 74- 540) for operating the clutch. Extended through dashboard I2 is emergency brake operating handle I6 guided within sheath I! rigidly supported within dashboard l2.

When said handle I6 is shifted inwardlyinto the'body of the vehicle, the emergency brake is set on, and when the same is released for shifting into the opposite direction the emergency brake is released.

The present locking device, co-operating with said clutch operating bar I3 and said emergency brake operating handle I6, includes plate I8,

' which is affixed to the outer face of foot board II operating bar I 3 in a longitudinal relation. Said 20.

,ing movement of said clutch operating bar I3 in U-shaped member 22 normally permits free shiftthe direction to or away from plate I8 and between the two wings of said U-shaped member 22. Each of the two, wings of said U-shaped member clutch operating bar I3 away from foot board II 22 is provided, adjacent its free end with a longitudina1slot 23, for accommodating therewithin locking tongue 24 as it shifts into or out of slots 23.

Integrally formed with said tongue 24 is extension 25 which is substantially in a transverse relation with said tongue 24. Substantially at the point of juncture with said extension 25, said tongue 24 is set and pivoted upon screw 26.

Said screw 26 is passed through said tongue 24 and through sleeve 21, and is afiixed or riveted to plate I8. Set, upon said screw 26, and adjacent the head thereof, is washer 28. Interposed between said Washer 28 and the adjacent face of tongue 24 is coil spring 29, one end of which is extended along the adjacent faces of said tongue 24 and said extension 25 and is bent transversely of said extension 25. The bent end abuts the adjacent edge of said extension 25, as at 30. The opposite end of said coil spring 29 is extended along the plane of the adjacent face of said washer 28, and

is formed into hook 3|, which is looped around pin 32, which is riveted by one of its ends to plate I 8.

Normally said coil spring 29 is under an expanding tension for urging the ends thereof into opposite directions, that is away from each other. Since the ends of said coil spring 29 are anchored to said extension 25 and pin 32, tongue 24 will remain out of slots 23 and out of the path of the shifting movement of the clutch operating bar I3 due to the pressure exerted upon extension 25 by the co-operating end of said coil spring 29, as is clearly seen in Fig. 3.

Aflixed to the free end of extension 25 by means of screw 33 is coil spring 34, the opposite end of which is affixed to cable or wire 35, the latter passed through guiding staple 36, and anchored by its opposite end to handle I 6, as at 31.

From the hereinabove description it will be readily apparent that when emergency brake operating handle I6 is pulled inwardly into the body of a vehicle for setting the emergency brake, coil spring 34 and cable 35 will be simultaneously pulled therewith. This operation exerts pulling force upon extension 25 in an upward direction for shifting the same and tongue 24 angularly for driving said tongue 24 into slots 23 and position ing the same rearwardly of clutch operating bar 13 and in the path of the shifting movement of the latter, as is clearly seen in Fig. 2.

The last hereinabove-described operation brings said tongue into an operative position, and renders said clutch operating bar 13 inoperative. By virtue of this condition the motor vehicle driver will be unable to operate the vehicle until clutch operating bar I3 is first released, and this cannot be done until the emergency operating handle is shifted into an inoperative position for releasing the emergency brake. Thus, in effect the motor vehicle is rendered inoperative as long as the emergency brakeis continued to be in an operative position:

Although the present device is shown to operate with clutch operating bar l3, it is to be understood that the same may be adapted for use in connection with other operating parts of the vehicle as accelerator operating mechanism, the brake operating parts, or many others, with slight or no modifications thereof.

Although coil spring 34 may be entirely eliminated if desired, and cable 35 may be directly,

connected with extension 25, but in that latter event the length of the cable employed. must be accurately determined in advance of aifixing of plate l8 to foot board ll. Coil spring 34, being expansible, will permit affixing of plate l8 to foot board ll either nearer to or farther away from handle [6 within areasonable range of the distance therebetween.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. As an article of manufacture, a lockingdevice for motor vehicles comprising a plate, a pair of spaced wings rigidly mounted upon said plate in position to receive a lever therebetween, said wings being provided with registering openings, a locking member pivoted to said plate in position to extend through the openings in bridging relation between the Wings in the path of movement of the lever, a pin rigidly aifixed to said plate, tensioning means interposed between one end of said locking member and said pin for normally maintaining the opposite end of said locking member out of said openings, and an actuating member affixed to said first named end of said locking member for shifting said opposite end of said locking member into said openings against the action of said tensioning means.

2. In a motor vehicle, in combination with a vehicle operating mechanism including a shiftable member, and an emergency brake operating handle, a locking device for rendering said shiftable member inoperative on shifting said handle into an operative position, comprising a plate, a pair of Wings extending from said plate ina substantially perpendicular relation therewith, said shiftable member being receivable between said wings for shifting movement on a plane parallel to said wings, said wings being provided with transverse alined slots, alocking member pivotally supported by said plate for shifting movement into or out of said slots, and connecting means between said locking member and said handle, on shifting said handle into an operative position said connecting means actuating said locking member for shifting the same into said slots and in the path-of shifting of said shiftable member for rendering the latter inoperative.
